CHILL-PLATE FOR FLASKS.

SPECIFICATION forming part of Letters Patent No. 478,622, dated July 12,1892. Application filed June 6, 1891. Serial No. 395,381. (No model.)

To all whom it may concern.-

Be itknown that I, FRANK MARTY, a citizen of the United States, andaresidentof Anniston, in the county of Calhoun and State of Alabama,have invented a certain new and useful Improvement in Chill-Plates forFlasks, of which the following is a specification.

The object of myinveution is to provide chill-plates for flasks, whichare adaptedto receive and centrally seat the'core-print of the patternand also the core and to permit the bead-ring to be readily removedwithout detaching the chill=plate from the flask; and the inventionconsists in the construction and I 5 arrangement of parts hereinafterpointed out and claimed.

In the drawings, Figure l is a side view,

' partly in section, showing the lower part of'a twin pipe-flaskprovided with my improved 2o chill-plates. Fig. 2 is a sectional viewupon line 2 2 of Fig. 1, and Fig. 3 a sectional view 'upon line 3 3 ofFig. 2.

A and A represent the sides of atwin pipeflask hinged at a. ,Brepresents the pattern, 0 the sand, D the bead-ring, and E a base-platerigidly attached to one part of the flask and provided with openingsunder each chamber of the flask adapted to receive the core-seats, whichalso serve as chill-plates.

F is a bar hinged to the flask or, more properly speaking, itsbase-plateE at a and adapted to belocked at its free end to the flask orits base-plate by means of a U-shaped clamp f and wedge f or othersuitable means.

G is a plate mounted upon the hinged bar F and carrying core-seats g,adapted to take into the openings in the base-plate and serveas'chill-plates. These core-seats are provided 40 with annular taperingopenings adapted to receive and centrally seat the core-print of thepatterns and also the cores.

The operation is as follows: The hinged bar F is clamped to the flask,thereby holding the core-seats firmly in the openings in the base-plate.The patterns are placed in the flask, their core-prints taking into theannular openings in the core-seats and being centrally seated thereby.The bead-ring is slipped over the pattern. The sand is put in and rammedand the pattern withdrawn. The clampf is removed and the bar F swungdownwardly, withdrawing the core-seats from the base-plate su'lficientlyto permit the re moval of the bead-rings. The core-seats are againlocked in position, the cores inserted, and the castings made. By thisarrangement the base-plate and core-seats become a permanent part of theflask and the bead-rings can be removed by simply lowering the hingedplate, and the'same seat serves both for the pattern and the core.

I have illustrated the plate G as pivotally mounted upon the bar F insuch manner as to allow some loose motion while the coreseats are beingswung into position; but it is obvious that the bar may be rigidlyattached to the plate or they may be integral.

I claim as my invention 1. In combination with a pipe-flask A A, thebase-plate E, provided with openings to receive the core-seats, thepivoted bar F, and the plate G, carried by the bar F and provided withthe core-seats g, the internal diameter of the flasks being greater thanthat of the openings in the base-plate, whereby a fixed ledge or supportis provided for the sand, all substantially as shown and described.

2. In combination with a pipe-flask, a baseplate attached thereto andprovided with openings, a bar F, and means for looking it in position,and a plate G, pivotally mounted upon the bar and provided withcore-seats, substan tially as and for the purpose specified.

FRANK MARTY.
